Helios MIPS Bike Helmet

Giro ups the ante once again with the addition of Spherical Technology, an advance that allows the helmet's outer liner to rotate around the inner liner in a new ball-and-socket design. It also allows progressive layering of the inner and outer liners to provide more comprehensive protection and performance. This is on top of MIPS®, the market-leading brain protection system that helps reduce rotational forces upon impact. Bottom line, the best defense possible. Add to that Giro's Wind Tunnel vents, patented Roc Loc Air 5 fit system and you're state of the art.

• independent, in-mold liners with spherical ball-and-socket design; full lower hardbody coverage
• MIPS® brain protection system
• ionic anti-microbial padding
• Roc Loc® 5 Air adjustability
• 15 Wind Tunnel vents and deep internal channeling

Helmets are made of materials that can be damaged by many commonly available cleaners. Petroleum based solvents or cleaners are especially problematic. They can damage a helmet so that its protective capabilities are reduced. Many times this damage is not visible. For best results, clean the helmet using a soft cloth or sponge, warm water and mild soap.
